Robert Durst is one of the more sympathetic alleged serial killers I've seen interviewed on television. He's not folksily unhinged, like Charles Manson, or flatly terrifying, like Jeffrey Dahmer. He seems like any other New York eccentric. He carries a backpack, wears little sneakers and toddles around New York City, Starbucks Americano in hand. He speaks in a nasal drawl, his voice steady, never rising or falling above a certain pitch (except for some stray whispers).
